Taxifolin (Dihydroquercetin) is a flavonoid in many plants such as Taxus chinensis, Siberian larch, Cedrus deodara and so on.

(±)-Taxifolin ((±)-Dihydroquercetin) is the racemate of Taxifolin, a flavonoid commonly found in onion, silymarin, French maritime pine bark, and Douglas fir bark, with anti-tyrosinase and anti-fibrotic activity.Taxifolin is an inhibitor of collagenase, with an IC 50 value of 193.3 μM. Taxifolin is a free radical scavenger with antioxidant capacity.

(-)-Taxifolin is the less active enantiomer of Taxifolin, demonstrating vital anti-tyrosinase activity and notable inhibition against collagenase (IC50 = 193.3 μM). It is valued as an essential natural compound showing antifibrotic potential, while also acting as a capable free radical scavenger and possessing antioxidant capacity.
